To all whom/l it mag/'concern' Be it known that I,'JOHN L. PowERs,'acitizen of theLUnited States, residing at Peoria,

in the county of Peoria and State of Illinois,

have invented certain new and useful Improvements in Fly-Escapes forScreens; and

do hereby declare that the followingf` is a full, clear, and exactdescri tion of the inven- U tion, which will enable ot ers 'skilled inthe screens.

- mit insects to pass from a room into the open A fur-ther Object is teprovide a device for permitting insects t'o gain the open air withz oA`improved devices attachedthereto. l

out fear of others entering'from the outside.

I A still further object is to make an attachment for screens that canbe put in place in a few seconds time.

Another obj ect is to `provide an escape with a bright surface, so as toattract the insects to it, and thus lead them tothe escapeopening. v

Another .object is to provide a device for the purposes described thatcan be placed upon a screenl without rendering the 'said screen weak atthe point of attachment.

' In the accompanying drawings, Figure 1 is a view'of awindow-screen,showing two my 1g. 2 is a sectional edge view of the screen, showingmanner of attachment of the device and its relation to said screen. Fig.3 is a perspective view-of the device, showing manner of attachment tothe wire screen. Fig. 4. is a viewl of the form of the device forming'part of myinvention before being formed.

The screen is represented by A, having in its two upper corners twohoods B, preferably of sheet metal. These hoods are formed as shown inFig. 3, having an outwardly and y screen and serve to hold the lbody Cin the position shown, it being seen that when placed upon said screenthere is greater space etween the lower edge of the body and the screenthan atI the top. The said-body extends somewhat above the top of theend portions D and has a lateral extension E, adapted te en age thescreen for securing purposes, as now be described. In placsaid bodybeing in addition.

ends is now bent back upon the body` and the site direction by the endsD leaving the s or openingF, the screen-wires being stretched, L.asindicated in Fig. 3, in so doing.

ing the device in osition for service on the screen a-horizonta slit `1smade 1n the latter vwhere'it isl desired to locate the exit. The

slit is preferablymade of a length equal to the length of the body C,the extensions E of remaining lone pushed through the slit behind vthescreen-wire, so that the end D adjacent thereto bear's against the endof the slit. Then the other end of the device is raised and pushedthrough the slit, after which Athe folded-over extension'E isstraightened out,

I the device then appearing as shown in Fig. 3.

In inserting the d evice it is toy be observed thatl the upper edge ofthe wire extends Fig. 2, pushing that edge outward andaway 'from theadjacent edge. Itis seen also that in pushing the device into place thesaid adjacent or ower edge is pushed in the opj Preferably, though notnecessarily, a wire G is secured in the lower edge of the device tostrengthen the metal and. also for aiding in securing it in place,'theprojecting ends thereof being pushed through the screen and turned up,as shown. Furthermore, if desired, a wire His passed through the middleOne of said slightly down outside of the body C, as in of the body Cnear the top, which enga es several meshes of the screen-Wire. This hods the screen close to the body and aids in maintaining the position ofthe device; but as a matter of fact neither the wire G nor the wire Hisnecessary to hold the device, the exten- IOO from a piece of sheetmetal, it being afterward bent into the desired form. I employ brighttin"for' the pur ose, by which the inner sidethereof next t e screenwill reflect light.

Since insects will approach a window because of the light, they will forthe same reason be attracte to the bright surfacefof the tin, and

thus be guided to the outlet. The opening of said outlet is upward andoutward, since itv IIO is the habit of insects to move upward, l

rather than downward.. In passing out they will either move up thebright tin or on the screen itself. When once outside, there is no fearof return, as they will not move downward outside the screen nor willthey a ain pass over the rough edge of the screen W ere it is cut. Thesurface of the tin within the room is to be painted the same color asthe screen, so as to be inconspicuous.

I am aware that fly-escapes of this class are not new; but there arenone, in so far as I have been apprised, that are constructed as mine iswith the bright surface for attracting the iies and the raw edges of thescreen caused by the ends of the cut wires.

I'claim* 1. In combination with a window-screen, a iiy-escape devicecomprising a hood secured to the inside of the screen, there being aslit in the latter to create an outwardly and upwardly positionedopening for admitting the `top edge of the hood said hood forming oneside of the opening and the rough-cut edge of the screen forming theother side of the opening as and for the purposes set forth.

2. In combination with a window-screen, a ily-exit device comprising ahood secured to the inside of the same, there being a slit in the latterto create an outwardly and upwardly extending opening to admit the topedge of the hood, said hood forming one side of the opening and therough-cut edge of the screen forming the other side of the opening,

said hood having end extensions for holdin it away from the screen atthe bottom an also to close the space between the ends of the hood andthe screen substantially as shown. A

3. In combination with a Window-screen, a hood having its upper ed einserted through the screen, there being a s it in the latter for thepassage of said edge as shown, one of the rou h-cut edges of the slitforming one side of t e opening for exit of the flies, projections onthe hood at the top for engaging the screen, and members at the bottomthereof for engaging the screen, the hood having end portions to closethe spaces between the ends of the hood and the screen as shown anddescribed.

4. In a {1y-escape, the hood B having the ends D D at right anglesthereto, the screen to which the hood is attached, there being a slit insaid screen for receiving the top of the hood, end projections E E atthe top of the hood for en agin the screen as described and shown, t een s D D serving to open the said slit in the screen to constitute anopening for the eXit of insects, and the wires G for assisting insecuring the hood in place.

In testimony whereof I afliX my signature in presence of two witnesses.
